Begonia plant named ‘HV01B1’

ABSTRACT

A new and distinct  Begonia  cultivar named ‘HV01B1’ is disclosed, characterized by its bright green foliage with a notched margin and bright yellow/orange and red flowers. The new cultivar is a  Begonia,  typically suited for ornamental container use.

Latin name of the genus and species: Begonia elatior.

Variety denomination: ‘HV01B1’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a chance discovery in an existingpopulation of Begonia elatior plants. The new variety originated as anaturally occurring, whole plant mutation of the parent variety, theunpatented commercial variety, Begonia elatior ‘Carnaval.’ The newvariety was discovered by the inventor, Jos ten Have, a citizen of theNetherlands, in the Summer of 2004 at a commercial greenhouse inMaasland, the Netherlands.

After selecting and isolating the new cultivar, asexual reproduction ofthe new cultivar ‘HV01B1’was first performed in the same commercialgreenhouse by vegetative cuttings in the winter of 2004. ‘HV01B1’ hassince produced several generations and has shown that the uniquefeatures of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘HV01B1’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘HV01B1’. These characteristics incombination distinguish ‘HV01B1’ as a new and distinct Begonia cultivar:

-   -   1. Bright green foliage.    -   2. Distinctively notched foliage margins.    -   3. Distinctive orange-yellow flowers with red margin.    -   4. Folded, ligulate floret.

PARENTAL COMPARISON

Plants of the new cultivar ‘HV01B1’ are similar to the parent ‘Carnaval’in most horticultural characteristics. However, ‘HV01B1’ differs inproducing foliage with a notched margin not found on ‘Carnaval.’Additionally, ‘HV01B1’ produces a larger flowers, of a different shapeand brighter color than ‘Carnaval.’

COMMERCIAL COMPARISON

Plants of the new cultivar ‘HV01B1’ are best compared to the parentvariety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘HV01B1’ grown in a greenhouse in Maasland, theNetherlands. This plant is approximately 10 weeks old, shown in a 10 cmpot. The photograph was taken using conventional techniques and althoughcolors may appear different from actual colors due to light reflectanceit is as accurate as possible by conventional photographic techniques.
